Title: Process for hydrosonically microaperturing thin sheet materials
Inventor: JAMESON LEE KIRBY
IPC: B26F1/26
Filed: 1991-12-16
Abstract: ABSTRACT OF THE DISCLOSURE   A method  for forming microapertures  in a thin sheet material where the area of each of the formed apertures generally ranges from about 10 square micrometers to 100,000 square micrometers is disclosed. The method includes the steps of (1) placing the sheet material on a pattern anvil having a pattern of raised areas wherein the height of the raised areas is greater than the thickness of the sheet material: (2) conveying the sheet material, while placed on the pattern anvil, through an area where a fluid is applied to the sheet material;  and  (3)  subjecting  the  sheet  material  to  a sufficient amount of ultrasonic vibrations in the area where the fluid is applied to the sheet material to microaperture the sheet material in a pattern generally the same as the pattern of raised areas on the pattern anvil.

Title: Multiprocessor system and message passing controller thereof
Inventor: NOBUYUKI OOBA
IPC: G06F13/36
Filed: 1992-01-23
Abstract: MULTIPROCESSOR SYSTEM AND MESSAGE PASSING           CONTROLLER THEREOF                            ABSTRACT        Upon requesting message passing, a processor notifies the request to another processor by designating identifiers of candidate destination processors and the upper limit UNR and  the  lower  limit  LNR  of  the  number  of  destination processors. A counter counts acknowledge signals from the candidate destination processors. A comparator compares the count value with the lower and higher limit values. If the count value is not less than the lower limit value,  the sending processor determines that it can perform message passing and selects processors, as many as the upper limit number, from the candidate destination processors according to a  rule;  then  initiates  the  message  passing  to  the processor thus selected.

Abstract: A microprocessor controlled wrapping machine including a separate SCR drive driving a corresponding permanent magnet motor, wherein an incremental optical encoder is coupled with each permanent magnet motor to provide a feedback signal indicative of motor position to a microprocessor. Both a main motor, which drives the infeed conveyor and the cutting head assembly, and a finwheel motor are used in combination with the SCR drive and an incremental optical encoder to provide a low cost alternative to a servo amplifier-controlled motor drive . Both the finwheel motor and the main motor are independently controlled from one another as a function of an oscillator, which forms a portion of the microprocessor circuit, and as a function of input switches and the respective feedback signal provided by the respective incremental optical encoder. The present invention provides a low cost alternative to wrapping machines incorporating expensive servo amplifier-controlled motor drives. Using an incremental optical encoder, the associated motor speed can be precisely controlled.

Inventor: DO CUONG D
IPC: B42D15/10
Filed: 1992-03-13
Abstract: A card reader for reading data recorded on a magnetic stripe on a card includes a guide for guiding the card along a path past a transducer head. A gimbal arrangement mounts the head on the end of a mounting shaft which is journaled in the end of an arm for free rotation about an axis parallel to the stripe as it moves along the path. The arm swivels about a transverse axis perpendicular to the stripe and is biased to bring the head into the guide path through a head opening.          The head has a leading bevelled surface so that a card inserted in the path will lift the head which will then ride firmly on the stripe. By virtue of the free rotation of the head about an axis parallel to the stripe, the device adjusts for any lack of parallelism between the head and the magnetic stripe.

Title: Method of manufacturing profiles
Inventor: DRESSLER HELMUT
IPC: B29C48/49
Filed: 1992-05-25
Abstract: ABSTRACT OF THE DISCLOSURE A method for manufacturing profiles from molten polymer materials by way of extrusion wherein the melt stream of second polymer material is channelled in the direction of flow into the main melt stream before the actual shaping process takes place and wherein the united melt streams are shaped in the extrusion die to form a profile extrudate which can be cut to length and removed after cooling. The degree to which the second polymer material dilates in the main melt stream is controlled by defining the distance between the injection point and the point at which the united melt streams enter the extrusion die and/or by defining the cross-sectional dimensions of the clear injection aperture for the second polymer material.
Patent CA-2075305-A1 (CA)
Inventor: BAUM RICHARD I
IPC: G06F9/32
Filed: 1992-08-05
Abstract: Provides relatively simple ways to obtain and control extenders (EXRs) for extending the size of small real and absolute addresses (up to 31 bit) to enable them to locate data or program entities anywhere in a very large memory (greater than 2**31). The EXR is concatenated to the high-order end of a conventionally-generated real or absolute address of less than 32 bit size to provide a real/absolute address of greater than 31 bit size (e.g. 63 bits). Each EXR value defines a section of a very large memory. The type of EXR location being used is indicated by having a CP extended address mode (CPEAM) field in a control register (CR). The CPEAM field indicates if the CP EXR field is associated with ARs, PTEs, STEs or ASTEs, or if a compatibility mode exists requiring no extender. When a CP program operates in the DAT-OFF mode, the EXR is contained in a register associated with a base register being currently used for operand address generation. When the CP is operating in DAT-ON mode, several different types of fields may be indicated, and the indicated EXR type is accessed during the address translation process, such when accessing an ASTEs, STE or PTE. The EXR field associated with the ASTE, STE or PTE is not used in the address translation process, but are only for address extension. By not affecting the translation process, the disclosure maintains downward compatibility for programs providing conventional small (e.g.31 bit) translated real addresses. Furthermore, an I/O EAM field is provided in a control block with each asynchronous I/O program to indicate the type of location being used for an I/O EXR field for providing the I/O EXR. The IOEAM field indicates if the I/O EXR field is associated with an ORB, CCWs, or IDAWs, or if a compatibility mode exists requiring no extender for I/O addressed data. This allows the I/O data of an I/O program to be mapped into one or plural sections of a very large memory, which may be the same or different from the section(s) addressed by the CP EXR.   <IMAGE>

Abstract: Recalculation of electrostatic target values in a tri-level imaging apparatus are utilized to extend the useful life of the photoreceptor (P/R). The increase in residual voltage due to P/R aging which would normally necessitate P/R disposal is obviated by resetting the target voltage for the full ROS exposure when it reaches its exposure limit with current P/R conditions. All contrast voltage targets are then recalculated based on this new target. The new targets are calculated based on current capability of the overall system and the latitude is based on voltage instead of exposure.

IPC: A47B96/20
Filed: 1992-10-28
Abstract: An appliance cabinet such as a refrigerator cabinet is formed of sheet steel which is textured by coining along one surface and provides a substantially smooth surface on the opposite  side.   The coining operation results  in shallow,  projecting irregularities on the substantially smooth side of the sheet steel.  Non-textured cabinets are formed by bending and joining the sheet steel to form a cabinet shell having the textured side of the sheet steel on the inside and a substantially smooth surface of the sheet steel on the outside.  When a finished paint coating is applied to the substantially smooth side, a leather-like surface appearance results.  When the sheet steel is bent and formed into a shell for a cabinet with the textured side on the outside,  a textured cabinet results.   By forming both types of cabinets from the same sheet steel, manufacturing savings result because only one type of sheet steel must be procured and inventoried.
